"Have mercy upon me, O God, according to Your lovingkindness, according to the multitude of Your tender mercies, blot out my transgressions." Psalm 51.1David's sin was extremely serious. However, every sin is deserving of forgiveness, as long as there is sincere repentance.
David obtained repentance and forgiveness because of his sincere confession.
Today, the same mercy is available to all those who seek it.
